Emac monitor goes black – slap brings it back to life
Last couple of days my emac monitor will just shut down and go black, just like an old TV tube packing up used to. It won't return on restart, but did return a couple of times after I took out mains lead from side of computer, let it rest, then tried again. However, today, this solution didn't work, but a tap to the side of the computer did get the screen going. I've read a number of different possible explanations for what might be the problem – everything from battery, to airport card to it's terminally ill, get a new computer, so don't really know what to do. Don't want to go and buy a new computer if all I really needed to do was change the battery. Any thoughts? Thanks in advance.
